Imipenem/cilastatin - Article Primaxin
Imipenem/cilastatin is a broad spectrum beta-lactam antibiotic containing equal quantities of imipenem and cilastatin. Imipenem, the active antibacterial agent, is rapidly degraded by the renal enzyme dehydropeptidase if administered alone. Cilastatin is a dehydropeptidase inhibitor, with no intrinsic antibacterial activity, and must be co-administered with imipenem to ensure its efficacy. Imipenem/cilastatin is marketed by Merck & Co. under the trade names Primaxin and Tienam.
